What is an easy solution to insert rendered HTML (no source code) into a Pandoc Markdown or LaTeX file?
I want to visualize an architecture diagram and tried Tikz but hadn't much success in a days worth trying and I figured HTML essentially can do the same and I am already familiar with it.
Only problem I have, is that I haven't found a good way to import it into Markdown.
What I figured so far:
PDF seems problematic as you can only insert entrire pages and you don't have labels.
Images would work I guess but I haven't found any native solution
HTML and PDF are so different that images are the easiest way to bring one into the other. The best choice to embed a vector image in PDF is via another, cropped PDF "image", with a high resolution PNG being the second best option. Open source tools like ImageMagick or GIMP can help you with these transformations.
My slightly more general advice would be to use Mermaid diagrams in combination with Quarto. Mermaid is a very 'Markdown-esque' way of drawing diagrams and is supported by GitHub and the like, so it can even be embedded in README files. Quarto is based on pandoc but is more opinionated and has many addons and improvements built on top (including support for diagrams).
In Power Automate Desktop, I'm trying to read Japanese text from Images using Windows OCR Engine but it is not able to extract Japanese characters into the text file.
Please let me know if there is any work around or solution for this problem.
Thank you in advance.
I am using Tesseract-OCR version 3.05 dev in python to OCR some documents. The main issue I have is with number 4 in the typewriter font. It almost always misses it and outputs either empty instead of 4 or some incorrect text.
I have uploaded a sample image.
I dont have to use tesseract as well, if you have suggestions on other (better) engines out there please let me know.
If you are looking for digits only you could add a whitelist which contains only digits. Example in c++:
tesseract::TessBaseAPI api;
api.SetVariable("tessedit_char_whitelist", "0123456789");
If that doesn't work I suggest you train tesseract-ocr for this specific font. A good and clear guide can be found here: https://medium.com/apegroup-texts/training-tesseract-for-labels-receipts-and-such-690f452e8f79#.mpllnzu57
Hope this helps solving your problem. :)
I'm looking for a OCR library that allows me to read text in an image, but only text that is circled. I want to get some feedback on Tesseract OCR for this task. It looks powerful but complex. HOw would it be used here, can I be trained for something like this? or should have to be extended?
Yes, Tesseract is fully trainable. And it just happens that it supports text in a circle also (pagesegmode 9). Give it a try.
I have been trying to find an answer or info related in creating an ebook for the iPhone with search capabilities of the text, and there is nothing clear. I just want to load several pages using HTML, PDF or any other way, and that is fine. The problem is to find a way to search the text on the HTML or PDF and provide a result for the user. Could anyone show me the best way to achieve this or show me a link of a BOOK or Tutorial, since I have been looking for parsers, search engines, and of course, everything is written for experts in programming. I know exactly how to use Xcode, the problem is if the only way to achieve this is to get into Java or HTML programming. Please Help!
It might not be what you're looking for, but if you have iWork installed, then Pages can export a document as an ePub file, and this can be searched with iBooks.
